It's 2020 - how do you build client-side applications? Carl and Richard talk to Brian Lagunas about his work in client-side development, largely around XAML (don't worry WinForms, we still love you!) - WPF, UWP and Xamarin.Forms. Brian leads the Prism open-source project that helps to build XAML-based applications, specifically WPF and Xamarin.Forms. The conversation digs into the problems around UWP and even a mention of Silverlight - and then the challenges of the other client-side platform, mobile!
